SAFETY PRECAUTIONS  
1.6  
READ THIS MANUAL BEFORE USING THE LT324 MOWER, IT IS ESSENTIAL THAT  
OPERATORS STUDY IT FOR THEIR OWN SAFETY.  
THE FOLLOWING PRECAUTIONS MUST BE TAKEN TO HELP PREVENT ACCIDENTS.  
A CAREFUL OPERATOR WHO USES COMMON SENSE IS THE SAFEST OPERATOR.  
TRAINING  
Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Learn  
how to stop the mower quickly in an emergency.  
Never allow children or people unfamiliar with these instructions to use the mower. Local regulations  
may restrict the age of the operator.  
Never mow while people, especially children, or pets are nearby.  
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or  
their property.  
Do not carry passengers.  
All drivers should seek and obtain professional and practical instruction. Such instruction should emphasise:  
The need for care and concentration when working with this machine.  
-
-
The need to slow down when making tight turning manoeuvres. Failure to take adequate care can affect  
stability leading to loss of control of the machine particularly when operating in transport mode.  
-
Control of a ride-on-machine sliding on a slope will not be regained by application of the brake.  
The main reasons for loss of control are:  
- Insufficient wheel grip.  
- Being driven too fast.  
- Inadequate braking.  
- The type of machine is unsuitable for the task.  
- Lack of awareness of the effect of ground conditions, especially slopes.  
- Incorrect load distribution.  
PREPARATION  
Check that the machine complies with all applicable regulations, including those in force when used on  
the public highway.  
While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when  
barefoot or wearing open sandals. Eye protection should be worn.  
Thoroughly inspect the area where the equipment is to be used and remove all objects which can be  
thrown by the machine.  
Never operate the machine without first checking that the operator platform latching mechanism is fully  
engaged and in good working order, refer - ‘OPERATOR PLATFORM LATCHING MECHANISM’.

SAFETY PRECAUTIONS  
PREPARATION  
Continued.  
Ensure that the cutterheads are fully raised with the latches and safety locks engaged in position before  
transporting the mower.  
Replace faulty silencers.  
Check the condition of the tyres and ensure that they are inflated to the correct pressures, refer -  
SPECIFICATIONS.  
This is particularly important if the machine is to be taken on the public highway.  
Check that the mower is in good working order, paying particular attention to the brakes and steering.  
Also ensure that the forward/reverse speed control pedals move freely to neutral when released.  
Before use, always visually inspect to see that the blades, blade bolts and cutting cylinders are not worn  
or damaged. Replace worn or damaged components.  
Check the mower hydraulic system, particularly the hydraulic hoses, fittings and hose supports. Worn,  
crushed or damaged hoses can burst, with risks to health and damage to the machine and surrounding  
turf areas.  
After refuelling and adding oil to the hydraulic oil tank ensure that the caps are replaced securely.  
Check that all linkages, connections and pivot nuts are secure and that wheel nuts are torqued correctly,  
refer - SPECIFICATIONS.  
Before operating the machine ensure that there are no foreign objects or liquids on the platform or ped-  
als - ALWAYS KEEP THE OPERATOR PLATFORM CLEAN/CLEAR.  
OPERATION  
Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect.  
Mow only in daylight or in good artificial light.  
Before attempting to start the engine, engage the parking brake, disengage the cutterhead drive system  
and ensure that the forward/reverse speed controls are in the neutral position.  
Never operate the machine without first checking that the operator platform latching mechanism is fully  
engaged and in good working order, refer - OPERATOR PLATFORM LATCHING MECHANISM.  
Stored energy devices are charged when the outer wing units are in transport position. Always operate  
the relevant lift controls to provide hydraulic support for the wing units suspensions before attempting  
to release the transport latches.

SAFETY PRECAUTIONS  
1.8  
OPERATION  
Continued.  
Do not use on a slope of more than 19 degrees. Where ground conditions are such that there may be a  
risk of the mower rolling over, the requirements of SI 1998 No 2306 "Provision and Use of Work  
Equipment Regulations" should be considered, refer - INTRODUCTION - Optional Extras.  
Ground conditions affect traction. Particular conditions may not permit safe operation on the slope lim-  
its stated.  
Remember there is no such thing as a "safe" slope. Travel on grass slopes requires particular care. To  
guard against overturning or loss of traction when travelling or mowing on a slope:  
-
-
-
-
-
-
-
-
Exercise extreme care when changing direction on a slope.  
Do not stop or start suddenly.  
Engage drive slowly.  
Keep machine speed low.  
Avoid tight turns.  
Stay alert for humps, hollows and other hidden hazards.  
Keep away from sharp inclines and steep drops.  
A thorough risk assessment should be carried out by a competent  
person before travelling or mowing on a slope.  
Never park on a slope.

SAFETY PRECAUTIONS  
OPERATION  
Continued.  
Watch out for traffic when crossing or near roadways.  
Use extreme caution when reversing.  
Disengage the cutterhead drive system before crossing surfaces other than grass.  
When using the machine, never direct discharge of material towards bystanders or allow anyone near  
the machine while in operation.  
Never operate the mower with defective guards, shields or without safety protective devices in place  
and in good working order.  
Do not change the engine governor settings or overspeed the engine. Operating an engine at excessive  
speed may increase the risk of personal injury.  
Before leaving the operator's position:  
- Disengage the drive to the cutterheads.  
- Lift cutterheads to the transport position and securely lock the safety latches  
or alternatively lower cutterheads to the ground.  
- Change into neutral and set the parking brake.  
- Stop the engine and remove the ignition key.  
Engage the parking brake, disengage the drive to the cutterheads, stop the engine and remove ignition key :  
- Before releasing blockages.  
- Before checking, cleaning or working on the mower.  
- After striking a foreign object. Inspect the mower for damage and make  
repairs before restarting and operating the equipment.  
- If the machine starts to vibrate abnormally ( check immediately ).  
- Before refuelling.  
- Before making cutterhead adjustments.  
Disengage the drive to the cutterheads when transporting or not in use.  
Reduce the throttle setting during engine run - out.  
Never work on the mower when the engine is running.  
Always keep feet and hands well away from the cutting cylinders when making adjustments.  
Never operate the mower without first checking that the operator platform is securely latched.

MAINTENANCE AND STORAGE  
Take care when rotating a cutting cylinder as this can cause other cylinders to rotate.  
When the machine is to be parked, stored or left unattended, lift the cutterheads to the transport position  
and engage the safety locks or lower the cutterheads to the ground.  
Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.  
Allow the engine to cool before storing in any enclosure.  
To reduce the risk of fire, keep the engine, silencer, fuel tank and battery compartment free of grass, leaves  
or excessive grease.  
Frequently check fuel lines and fittings for cracks or leaks and replace if necessary.  
Replace worn or damaged parts for safety.  
Ensure that all safety decals are properly secured and in good condition.  
If the fuel tank has to be drained, this should be done outdoors.  
Be careful during adjustment of the machine to prevent entrapment of the fingers between moving blades  
and fixed parts of the machine.  
Never attempt to disconnect any part of the hydraulic system before de-pressurisation. This may be  
achieved by lowering all cutterheads to the ground, stopping the engine and removing the ignition key.  
Avoid skin or eye contact with hydraulic or diesel fluids. Wear protective clothing.  
Leaking fluids under pressure can penetrate the skin or eyes, causing serious injury.  
Always use a piece of cardboard or paper when searching for leaks.  
Health and Safety at Work Act:

INTRODUCTION  
The Hayter LT324 Triple Turf Mower is a diesel engine powered self propelled machine with hydraulic  
systems for ground drive, cutterhead drives and steering. The machine operates in two wheel drive with  
automatic four wheel drive on demand. A differential lock function may be selected. The transmission  
system is converted automatically to engage drive to all 4 wheels when the machine speed decreases as  
a result of front wheel traction slip. 2WD is automatically re-engaged when traction slip is reduced.  
The Hayter LT324 Triple Turf Mower is a precision built machine designed solely for cutting grass and  
similar low lying ground vegetation within the limitations stated in this manual. Use in any other way  
is considered as contrary to the intended use. Compliance with and strict adherence to the conditions  
of operation, service and repair as specified in this Operators Manual also constitute essential elements  
of the intended use. The way in which this machine is operated and maintained will have a profound  
effect on its performance and reliability.

OPERATING THE MOWER  
1.25  
SAFETY NOTICE  
WARNING: PREVENT ACCIDENTS - Before operating the mower it is essential that;  
- The operator reads and understands this manual.  
- The operator platform latching mechanism is fully engaged and in good  
working order, refer - OPERATOR PLATFORM LATCHING MECHANISM.  
- The daily maintenance checks have been properly carried out and the  
mower is in good working order.  
- The operator should wear safety clothing and eye protection. Failure to do  
so could result in risk to health and safety.  
- The area where the equipment is to be used is inspected and all objects  
which may be thrown by the machine are removed.  
Operate safely on slopes;  
It is essential to follow safe working practices when working on slopes. In  
order to avoid potentially hazardous situations, it is essential that the operator  
understands and observes the relevant safety precautions listed in this manual,  
refer - ‘SAFETY PRECAUTIONS’.  
OPERATOR PRESENCE CONTROLS  
Cutting Cylinder Drive Lockout: Drive to the cutting cylinders is only possible when the operator is  
seated. If the operator raises off the seat for a period of more than one second, a switch is activated and  
drive to the cutting cylinders is automatically disengaged. To re-engage drive to the cutting cylinders, the  
operator must return to the seat, then operate the cutterhead drive switch to the ‘OFF’ position before  
moving it back to the ‘ON’ position. If the operator rises off the seat for a brief moment during normal  
work, drive to the cutting cylinders is not affected.  
The engine can only be started with the cutterhead drive switch in the ‘OFF’ position.  
Engine Start Lockout: The engine can only be started when the forward/reverse travel pedal is released  
to the 'NEUTRAL' position, the cutterhead drive switch is in the ‘OFF’ position and the parking brake is  
engaged. When these circumstances are satisfied, switches are activated permitting the engine to be start-  
ed.  
Engine Run Interlock: Once the engine is started the operator must be seated before the parking brake is  
released for the engine to continue to run.  
With the engine running and the machine moving with the travel pedal depressed, the engine will contin-  
ue to run when the operator rises from the seat. If the travel pedal is then allowed to return to neutral the  
engine will cut out.  
WARNING: PREVENT ACCIDENTS - Do not operate the turf mower if the operator presence  
controls are defective in any way. ALWAYS replace faulty parts and check that they function  
correctly before operating the mower.

BRAKING SYSTEM  
Parking brake : Move the parking brake lever to its rear position to engage the  
parking brake. Do not operate the mower with the parking brake engaged.  
P
Parking brake engaged  
WARNING : PREVENT ACCIDENTS - The parking brake operates on the front wheels only. Do not  
park the mower on a slope.  
Service brakes : Service braking is achieved by the hydraulic transmission system. When the forward or  
reverse travel pedals are released or the engine speed reduced, service braking becomes effective and trav-  
el speed is automatically reduced. To increase the braking effect, push the transmission pedal into the neu-  
tral position. Service braking is effective on the front wheels only.  
WARNING : PREVENTACCIDENTS - The service braking system will not hold the mower at a stand-  
still. ALWAYS ensure the parking brake is engaged to park the mower at a standstill.  
Emergency braking : In the event of service brake failure, turn the ignition off to bring the mower to a  
standstill.  
WARNING: PREVENT ACCIDENTS - Take care when operating the emergency braking system.  
Remain seated and hold on to the steering wheel to prevent ejection from the mower caused by the  
front wheel brakes being applied suddenly when travelling.

WEIGHT TRANSFER / TRACTION ASSISTANCE  
A variable hydraulic weight transfer system is provided for improving tyre grip with the grass surface -  
‘Traction Assistance’.  
Hydraulic pressure in the cutterhead lift system provides a lifting force which reduces cutterhead weight  
on the ground and transfers the weight as a downward force onto the mower’s tyres. This action is  
known as ‘Weight Transfer’.  
To engage weight transfer: The amount of weight transfer can be varied to suit operating conditions by  
rotating the weight transfer hand wheel as follows;  
Release the lock wheel underneath the hand wheel 1/2 turn anti-clockwise and hold.  
Rotate the hand wheel:  
Tighten the lock wheel.  
- Anti-clockwise to reduce weight transfer.  
- Clockwise to increase weight transfer.

GENERAL OPERATING HINTS  
1.  
The rotational speed of the cutting cylinders should always be kept as high as possible in order to  
maintain the highest quality of cut. This in turn requires that the engine speed be kept as high as  
possible.  
2.  
3.  
4.  
The quality of cut will deteriorate if the forward speed is excessive. Always balance the quality of cut  
with the workrate required and set the forward speed accordingly.  
Never let the engine labour. Reduce the forward speed or increase the height of cut. Check that the  
cutting cylinders are not in heavy contact with their bottom blades.  
Regularly check the cutting cylinder to bottom blade adjustment every few hours even though cutting  
performance appears to be satisfactory. Heavy contact or excessive clearances between the cylinder and  
bottom blades will cause rapid wear to take place.  
5.  
6.  
Always disengage the cutterhead drive when travelling across ungrassed areas. Grass will lubricate the  
cutting edges whilst mowing. Excessive heat will build up if the cutting cylinders are run when not  
mowing and this will cause rapid wear to take place. For this reason it is also wise to reduce cutting speed  
when mowing lightly grassed areas or when the grass is dry.  
Cutting performance is best when cutting against the lie of the grass. In order to take advantage of this  
fact, the operator should attempt to alternate the direction of mowing between cuts.  
7.  
8.  
Take care not to leave uncut strips of grass at the overlap points between adjacent cutterheads by  
avoiding tight turns.  
It is generally wise to remove rear roller scrapers where conditions allow, as optimum grass discharge is  
achieved without them. Scrapers should be refitted when conditions are such that mud and grass start to  
build up on the rollers. When refitting the scraper wires care must be taken to ensure that they are cor-  
rectly tensioned, refer - MAINTENANCE - EVERY 50 HOURS.  
WARNING : PREVENT ACCIDENTS -Take care when travelling over obstacles such as roadside  
kerbs. ALWAYS travel at slow speed over obstacles to prevent damage to the machines tyres,  
wheels and steering system. Ensure that tyres are inflated to the recommended pressures.

CUTTERHEAD GENERAL INFORMATION  
The mower is designed to be used with MK3 200mm fixed or floating cutterheads or MK3 254mm  
fixed cutterheads.  
It is essential that the relationship between the bottom blades and the cutting cylinders are kept in good  
adjustment and that cutting edges are kept sharp to ensure good cutting performance, minimum power  
consumption and prolonged life for the cutting edges, refer - MAINTENANCE - Cutterheads.  
Fixed MK3 200mm/254mm Cutterheads: When the mower  
is set up with fixed cutterheads the height of cut is gauged by  
the rear roller and the cutterhead is allowed to pivot laterally to  
follow ground contours. This arrangement is normally  
recommended for general mowing requirements.  
(MK3 200mm Cutterhead illustrated).  
1D876P02A  
Floating MK3 200mm Cutterheads: When the mower is set  
up with floating cutterheads the height of cut is gauged by the  
front and rear rollers. The cutterhead is allowed to pivot fore  
and aft as well as laterally. This arrangement is recommended  
for high quality grass areas and performs well where grass is  
short and the ground undulations are severe.  
1D876P03A  
Grass deflectors: The rear grass deflectors must always be  
correctly fitted. The deflectors should be set as low as possible  
to deflect grass discharge to the ground.  
WARNING: PREVENT ACCIDENTS - Always ensure  
that the grass deflectors are angled below horizontal level,  
otherwise risks to health and safety may result.  
1D876P04B  
Height of cut gauge: An optional height of cut gauge is  
available to assist in achieving accurate cut height settings. It  
is suitable for both fixed and floating cutterheads.

CENTRE CUTTERHEAD HEIGHT OF CUT CORRECTION ADJUSTMENT  
With all cutterheads set at the same HOC via the indicator rings, it may be noticeable that the centre unit pro-  
duces a higher cut finish compared to the wing units. The centre unit is pulled and the wing units are pushed  
this presents marginally different cutting angles relative to the ground. The amount of HOC variation, which  
results from this will be influenced by the terrain but satisfactory results can usually be achieved by setting the  
centre cutterhead HOC indicator ring lower than the wing unit settings.

CUTTERHEAD CYLINDER TO BOTTOM BLADE ADJUSTMENT  
IMPORTANT : PREVENT DAMAGE - It is essential that the  
relationship between the bottom blades and the cutting cylinders is  
kept in good adjustment in order to ensure good cutting performance,  
minimum power consumption and prolonged life for the cutting edges.  
Carry out the following procedure before commencing work and re-check  
the settings every few hours.  
900  
Check that the cutting cylinder is correctly set to the bottom blade by  
holding a thin piece of paper between the cutting cylinder and the bottom  
blade as shown. Carefully rotate the cylinder as shown and check that the  
paper is cut cleanly at all points along the length of the blade. Hold the  
paper at 90 degrees (right angles) to the bottom blade to obtain the correct  
cutting action.  
WARNING: PREVENT ACCIDENTS - Ensure that people are clear  
of the cutting cylinders as rotation of one may cause others to rotate.  
If adjustment is necessary proceed as follows;  
B
Release nut 'A' 1/4 turn both ends.  
Turn handwheel 'B' each end alternately whilst rotating the cutting  
cylinder backwards until the bottom blade is in 'fleeting' contact with the  
A
cylinder along its entire length. Re-check the cutting action along the  
length of the bottom blade using a thin piece of paper making marginal  
adjustments as necessary.  
Tighten nut 'A' both ends.  
If it is impossible to obtain a good clean paper cut across the entire length of the bottom blade it will  
be necessary to carry out the backlapping procedure to reprocess the cutting edges. In severe cases it  
will be necessary to regrind the cutting cylinder and the bottom blade, refer - BACKLAPPING /  
GRINDING.  
Do not be tempted to over adjust, thus causing heavy contact between the cylinder and bottom blade,  
as this will cause very rapid uneven wear to take place leading to tramlining and waviness of the cut-  
ting edges. The frictional losses will be high and a significant amount of power will be absorbed, thus  
reducing the power available for cutting. The heating effect due to friction will cause excessive expan-  
sion to take place which will further aggravate the situation by increasing the contact pressure.  
If the cutterheads are allowed to operate for more than a few hours without adjustment the running wear  
will eventually cause the cylinder to run out of contact with the bottom blade. At this stage very rapid  
rounding of the cutting edges will occur as grass and abrasive particles pass through the  
clearance between the blades.  
Lack of attention to adjustment can therefore be foolhardy as maintenance costs will escalate. The qual-  
ity of cut will also be seriously affected as will the health and growth of the grass.  
An experienced operator will notice when a cutterhead starts to go out of adjustment; when the grass  
ceases to be cut cleanly and the cut ends become ragged.

CUTTERHEAD BACKLAPPING  
This process is recommended for restoring the sharp cutting edges to  
cylinders and bottom blades which are essential for good quality grass  
cutting.  
This process can only deal with a small amount of metal removal to restore  
the cutting edges. If the blade edges are seriously worn or damaged it will  
be necessary to remove the component parts and have them reground.  
The backlapping process:  
1. Check that the mower engine is switched off and the parking brake applied.  
2. Adjust the cutting cylinders to the bottom blades to obtain ‘fleeting contact’.  
3. Apply a medium grade detergent based carborundum paste to the cutting  
edges of the cylinders with a long handled brush.  
80 Grade Carborundum paste  
Hayter Part No:  
0,45 kg  
63-07-088  
63-07-086  
11,25 kg  
4. Ensure that the area surrounding the cutterheads is clear of people and keep  
hands and feet clear of the cutting cylinders during the period when the  
mower engine is running.  
5. Sit on the operator seat, start the mower engine and set the engine speed at  
idle.  
6. Operate the cutterhead drive switch to the 'reverse/backlap' position for a  
period of time and listen to the grinding action .  
7. Operate the cutterhead drive switch to the 'off' position and switch off the  
mower engine when the grinding action has stopped.  
900  
8. Thoroughly clean the blade edges and adjust the cutting cylinders to the  
bottom blades. Check that a thin piece of paper can be cut cleanly at all  
points along the cutting edges while rotating the cylinders by hand.  
9. If further backlapping is necessary repeat steps 2 to 8.  
10. Thoroughly remove and wash off all traces of the carborundum paste from  
the cylinders and bottom blades.

CUTTERHEAD GRINDING  
It will be necessary to carry out a grinding operation to correct cylinder spiral edges or bottom blade  
edges which have become excessively rounded or distorted. Bottom blades which are nearing the end  
of their wear life should be replaced. The new blades should be ground on their holders prior to fitting,  
refer - CUTTERHEAD BOTTOM BLADE REPLACEMENT. When grinding operations are necessary  
it is essential that both cylinders and bottom blades are ground at the same time. The only exception to  
this rule is when a new cylinder is fitted in which case it is only necessary to grind the bottom blade.  
All such grinding operations should be carried out by your dealer on a quality, well maintained  
cylinder/ bottom blade grinding machine.  
CUTTERHEAD BOTTOM BLADE REPLACEMENT  
Remove the bottom blade holder by removing the three fixing bolts at each end and withdraw from the  
cutterhead. Remove the worn bottom blade and discard the countersunk screws and securing nuts. Fit  
the new blade to the holder and loosely assemble with new countersunk screws and securing nuts.  
Tighten the centre bolts to a torque of 40 Nm. Continue by tightening the remaining bolts to the same  
torque by working from the centre out towards the blade ends.  
The new bottom blade must be ground on its holder prior to refitting to the cutterhead.  
Adjust the cutting cylinder position to give adequate clearance for fitting the new bottom blade holder.  
Refit the bottom blade holder assembly to the cutterhead using the original fixing bolts and tighten to  
a torque of 35 Nm. Finally adjust the cylinder to the bottom blade, refer - CUTTERHEAD CYLINDER  
TO BOTTOM BLADE ADJUSTMENT.
